How to calculate Critical Damage ??
150% base means the base multiplier without any bonuses from gear or traits.
-100 dmg hit will crit for 150 dmg (100 * 1.5)
Power makes your hits higher.
-120 dmg hit will crit for 180 dmg (120 * 1.5)
% Critical Damage affects your critical multiplier. For example your gear gives you +20% critical damage, your multiplier will be 150% + 20% = 170%
-100 dmg hit will crit for 170 dmg (100 * 1.7)
Precision only affects how often you will crit.
So both, power and % critical damage, affects the size of your crits. Just in different way. You need both to maximize them.
This is want I want to know !!
